Abstract
A power unit and a solid-state transformer supply power to a control module in the power unit by using a first subsidiary power supply circuit and a second subsidiary power supply circuit and improve operation reliability of the power unit. The power unit may include the first subsidiary power supply circuit and a first power circuit. The first power circuit includes an alternating current/alternating current power main circuit and a first control module. The alternating current/alternating current power main circuit is coupled to a grid power supply system to supply power to the alternating current/alternating current power main circuit through the grid power supply system. An input end of the first subsidiary power supply circuit is coupled to a bus of the alternating current/alternating current power main circuit. An output end of the first subsidiary power supply circuit is coupled to the first control module.
